24V ac/dc operation, 1- or 2-Channel InputOriginal Instructions• Monitors one or two safety switches for a contact failure or wiring fault• Two output switching channels for connection to control-reliable power in-terrupt circuits• Auto reset or monitored manual reset• Design complies with standards UL991, ISO 14119, and ISO 13849-1(EN954-1) (Safety Category 2, 3 or 4)• For use in functional stop category 0 applications per NFPA 79 and IEC60204-1• 6 amp safety output contacts• Plug-in terminal blocks• If terminal blocks are swapped, Module remains functional with no loss ofsafety functionOverviewThe GM-FA-10J Gate Monitor Safety Module (the “Safety Module”) is used to verify the proper operation of coded magnetic safetyswitches and positive-opening safety switches by monitoring a normally open (N.O.) and a normally closed (N.C.) contact from eachswitch. It can also be used to monitor and verify the correct state of two redundant current-sourcing PNP signals. (One PNP source mustbe Normally OFF and the other Normally Conducting for each input channel.) In a typical application, two safety switches (individuallymounted) indicate the open or closed status of a gate, moveable guard, or barrier (all called “guards” throughout this document).Two functions of the Safety Module are:1. To monitor the contacts and wiring of safety switches for certain failures and to prevent the machine from restarting if the switch orthe Module fails, and2. To provide a reset routine after closing the guard and returning the inputs to their “closed” condition. This reset function may berequired by machine safety standards.The Safety Module monitors each switch for complementary switching; each channel must have one open (OFF) input and one closed(conducting) input at all times. These inputs must always be in opposite states and must switch state within 1 second of each other.Channel 1 has a “guard closed” condition when S11/S13 is closed and S11/S12 is open. Similarly, Channel 2 has a “guard closed” condi-tion when S21/S23 is closed and S21/S22 is open (see Figure 2. Wiring to two 4-wire coded magnetic safety switches on page 7 andFigure 3. Wiring to two positive-opening safety interlock switches on page 7). The Safety Module also will detect and properly respondto a short circuit between the channels and a short circuit to other sources of power. The Safety Module will open the safety outputswithin 35 milliseconds of the switching of either channel when the guard opens.When the guard closes, debounce logic in the Safety Module’s inputs increases the reliability and repeatability of successfully resettingthe Safety Module and reduces the necessity of re-cycling the guard. This feature can result in increased efficiency of the machine, evenif the guard is misaligned or vibration is present.Important: Read This First!The user is responsible for satisfying all local, state, and national laws, rules, codes, and regulations relating to the use of thisproduct and its application.
